[meta-intel] [dizzy][PATCH 2/3] meta-crystalforest: add qat preferred provider

[Ong, Boon Leong]

>Your cover letter said crystal forest depends on qat15. Why are we setting it to
>qat16 here?

Crystal-forest depends on qat15
Highland-forest depends on qat16

Qat16 is chosen as default because that is to support coleto creek which is newer chipset.

This is from discussion in the past with Saul on splitting the recipe into qat15 and qat16
so that we can have those named folders containing versioned patches accordingly.
